NASA's Hubble Finds Universe Is Expanding Faster Than Expected

June 02, 2016Release ID: 2016-17 Missions: Hubble

When astronomer Edwin Hubble discovered nearly 100 years ago that the universe was uniformly expanding in all directions, the finding was a big surprise. Then, in the mid-1990s, another shocker occurred: astronomers...
Hubble Team Breaks Cosmic Distance Record

March 03, 2016Release ID: 2016-07 Missions: Hubble

NASA's Hubble Space Telescope is an amazing time machine; by looking back through space, astronomers actually look back through time. Now, by pushing Hubble to its limits, an international team of astronomers has shatter...
Hubble Finds Birth Certificate of Oldest Known Star

March 07, 2013Release ID: 2013-08 Missions: Hubble

You can't be older than your parents. But there is a nearby star that at first glance looks like it is older than the universe! Hubble Space Telescope astronomers are coming to grips with this paradox by improving the...
NASA's Hubble Breaks New Ground with Distant Supernova Discovery

January 11, 2012Release ID: 2012-02 Missions: Hubble

NASA's Hubble Space Telescope has detected a distant Type Ia supernova, the farthest stellar explosion that can be used to measure the expansion rate of the universe. The supernova is the remnant of a star that exploded...
Was the Real Discovery of the Expanding Universe Lost in Translation?
